Hopefully gpu hotplugging means in the future we can install a new graphics card the following way:
- tell software to make graphics card ready to be removed
- wait until software ready
- unplug graphics card
(3d apps are pauzed and rendering of windows is done by CPU)
- plug new graphics card in
- install drivers (installer graphics should be simple enough for CPU rendering to handle)

Don't see the benefit. How many times in a month does one replace it's GPU? And is it that bad to reboot? Come on...

Just because Windows does it doesn't mean Linux should be capable to do it as well.

In the general sense of being able to add/remove GPUs, lots of people do it multiple times per day. The most common is probably the Optimus scenario where a discrete GPU is enabled/disabled based on available power, but external GPUs are already in some laptop docking stations as well, a trend that's likely to increase as Thunderbolt support becomes more common. Adding the actual physical hotplugging of a card to this is more of a PCIe problem than a GPU problem.

But isn't there a big difference between just enabling/disabling a GPU chipset (and vice versa with another) and doing hotplugging??
